Hi there and welcome
Can you tell me please the error you get when you try to upload files to one drive?
ok, so what happens when you try to upload files?
ok... sorry I need more information here.
Lets start with exactly how are you uploading? Online via your web browser?
ok, if it is not erroring then it is saving but likely you set a different account when installing windows 10
Go to your drive here
Do you see the files listed there?
ok... so they are then uploading correct? If you now see them.
yes, I saw your last message, it means they are uploading when you save as you see the files listed.
Please be more specifc
when you just reply Files are listed this does not really make it clear
The files, the files you are saving, are they there? Yes / No ?
Then you are signing into windows 10 on another Microsoft account
Go to Control Panel, Users, add an account and add your correct Microsoft Email address.
Save this, restart the computer and sign into this new account then try to save.
Let me know the results please
Then tell me if you can upload
Go to Start, then select Settings > Accounts > Your account.
Select Sign in with a Microsoft account instead.
Follow the prompts to switch to a Microsoft account. You may need to verify your identity by entering a confirmation code.
sorry I do not understand what you mean with your message
yes I saw, and asked you to do the next batch of instructions.
Please do this
ok... not really sure why you would not do my last instructions.
But if you return I plead that you provide a lot more detail in your responses if you wish to have your problem fixed.
